Does anyone know if this 8 TB WD hard drive for $284 would be a good internal backup drive for one of my file server ? We write a
LAN backup to three internal backup drives each night. I hate to buy a 6 TB drive as our LAN backup is over 3 TB now. So I am
looking for the cheapest WD 8 TB hard drive.

Thanks,

I found out from a friend that the WD Purple drives do not spin down:

"When I was researching home surveillance systems that include a video recorder, the better and best models all had WD Purple HDs.
The are designed to withstand constant spinning and do not have an “internal feature” that spins them down after a certain amount of
time. Because they are designed to run constantly and in what could be a critical system they would be a good choice for a backup
situation."

Thanks ! I did not know that the purple drives do not spin down. Our LAN backup only runs 3 to 4 hours per day and I would rather
the drive spin down during the down time. I will wait for the WD 8 TB red drives to get back in stock at Big River. Right now the
only available drives are by exotic resellers. I wonder if WD is running out of helium ?
